Introduced in 1990 through a collaboration between Smith & Wesson and Winchester, the .40 Smith & Wesson cartridge was developed to offer a practical balance of cartridge size and performance in semi-automatic service pistols. Its development was influenced by the FBI's search for a suitable handgun cartridge following the 1986 Miami shootout, and it gained widespread adoption among law enforcement agencies throughout the 1990s. The cartridge uses a .400-inch nominal bullet diameter and was designed around a shorter case than the 10mm Auto, allowing it to function in more compact handgun platforms. Although its popularity has evolved over the years, .40 S&W remains a widely recognized chambering with a substantial installed base of pistols.
